Chrysanthemum plant named ‘Zanmugrape’

ABSTRACT

A  chrysanthemum  plant named ‘Zanmugrape’ characterized by its medium sized blooms with purple ray florets and prolific branching; natural season flowering date October 13; blooming for a period of 5 weeks.

Botanical designation: Chrysanthemum×morifolium Ramat.

Cultivar denomination: ‘Zanmugrape’.

RELATED CULTIVARS

This new plant cultivar ‘Zanmugrape’ is of the botanical classificationChrysanthemum×morifolium Ramat.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofchrysanthemum plant, botanically known as Chrysanthemum×morifoliumRamat., commercially known as a garden mum, and hereinafter referred toby the cultivar denomination ‘Zanmugrape’. ‘Zanmugrape’ is a product ofa breeding and selection program for outdoor pot mums (garden mums)which had the objective of creating new cultivars with a double typeinflorescence, a natural season flowering date around October 1,blooming for a period of 5 weeks. ‘Zanmugrape’ is a seedling resultingfrom a cross of the female parent 22173 with the male parent 17006.Plants of the new cultivar ‘Zanmugrape’ differ from plants of theparents in the following characteristics. (1) Ray-floret color. And (2)Natural season flowering date. (1) Plants of the seedling have purplecolored ray-florets, while plants of the female parent have pink coloredray-florets, and plants of the male parent have salmon coloredray-florets. (2) Plants of the seedling flower two weeks earlier in theseason than those of the female parent, and one week earlier than thoseof the male parent. The new and distinct cultivar was discovered andselected as a flowering plant by Henricus Cornelius Maria Jacobs on acultivated field in Rijsenhout, The Netherlands in 2010. The first actof asexual production of ‘Zanmugrape’ was accomplished when vegetativecuttings from the initial selection in 2010 were propagated further in acontrolled environment in Rijsenhout, The Netherlands. The new cultivarhas been found to retain its distinctive characteristics throughsuccessive propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum (ofabout 19 weeks) is shown in the accompanying drawings, the color beingas nearly true as possible with color photographs of this type.

FIG. 1 shows a plant of the cultivar in full bloom.

FIG. 2 shows the various stages of bloom of the new cultivar.

FIG. 3 shows the various stages of foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

The observations and measurements were gathered from plants grown outdoor in Rijsenhout, The Netherlands, under natural day length andtemperature and planted in week 25 in 2014, receiving drip irrigation.The natural blooming date of this crop was October 13. The averageheight of the plants was 29 cm. No growth retardants were used. No testswere done on disease or insect resistance or susceptibility. No testswere done on cold or drought tolerance. This new variety produces mediumsized blooms with purple ray florets blooming for a period of 5 weeks.From the cultivars known to inventor the most similar existing cultivarin comparison to ‘Zanmugrape’ is ‘Venus’ (U.S. Plant Pat. No. 14,378).When ‘Venus’ and ‘Zanmugrape’ are being compared the followingdifference is noticed: The difference of ‘Venus’ and ‘Zanmugrape’ istheir natural season blooming date, plants of ‘Venus’ flower earlierthan those of ‘Zanmugrape’.

The following is a description of the plant and characteristics thatdistinguish ‘Zanmugrape’ as a new and distinct variety.

The color designations are taken from the plant itself. Accordingly, anydiscrepancies between the color designations and the colors depicted inthe photographs are due to photographic tolerances. The color chart usedin this description is: The Royal Horticultural Society Colour Chart,edition 2001.
